How do i know when jock itch is gone completely? currently treating one thats been stubborn with lotrimin powder after multiple treatments. itching is gone, but skin color is a weird faded pinkish color?

If it’s not scaly or itchy anymore and the area is not growing,your tinea Cruris(jock itch) is gone.It may come back in the future.Use Terbinafine or Clotrimazole,etc. Treat your feet if also scaly or itchy.I think that one or more of the products you applied before, might have had a strong steroid and, the pinkish hue is skin atrophy.Most cases go back to normal in around a year.
